The difference between R22 and R410A air conditioning refrigerant

For the average person, the most contact with refrigerant comes from air conditioners. The refrigerant is the working medium of the air conditioning refrigeration cycle. The refrigerant absorbs heat when vaporized in the evaporator and releases heat when condensed in the condenser to achieve the purpose of refrigeration. However, because different models use different air conditioners, I will take you to understand the difference between the two most common refrigerants used in air conditioners, which are R22 refrigerant and r410a refrigerant.

1. Distinguish from the chemical composition

The chemical name of R22 is difluoromonochloromethane, which is one of the freons and belongs to hydrochlorofluoromethane Hydrocarbons. At present, R22 refrigerant still accounts for the largest proportion in the use of air conditioners, mainly some old-fashioned air conditioners are in use. Because R22 refrigerant contains 'cl' element, it has great harm to the ozone layer. It is currently being phased out.

R410A refrigerant is one of the currently positioned environmentally friendly refrigerants. It is composed of two quasi-azeotropic mixtures, mainly composed of hydrogen, fluorine and carbon. It is stable and non-toxic. Features such as superior performance. At the same time, since it does not contain chlorine, it will not react with ozone and will not destroy the ozone layer. In addition, the performance of air conditioners using new refrigerants will also be improved to a certain extent. R410A is the most suitable refrigerant to replace R22, which is recognized internationally so far, and it is popularized in Europe, America, Japan and other countries.

Second, the benefits of substituting R22 refrigerant

1. R410A is of low toxicity, and R22 is slightly toxic. It will be more secure in terms of safety in use.

2. For environmental hazards, the ozone layer destruction coefficient of R410A is 0, and the ozone layer destruction coefficient of R22 is 0.05. So R410A refrigerant has more advantages.

3. When using R410A, the total heat transfer characteristics of the system are larger than R22, so the system efficiency can be improved and the heat transfer area of u200bu200bthe heat exchanger can be reduced. The air conditioner is more smooth to use, and the chance of failure is much smaller.

Through the above introduction, you have a certain understanding of R22 refrigerant and R410A refrigerant. In the later use, it is mainly added according to the refrigerant model on the air conditioner. Do not add it randomly, which may cause damage to the air conditioner and personal danger. Of course, the later development of air-conditioning refrigerants will continue, and there will be better alternative products to replace them. At present, R410A refrigerant is the mainstream of future development. The market prospects will also get bigger and bigger.

At the same time, as the recent research of Arkool shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
